Which of the following modes of motion is exhibited by the particles of a solid?
- Vibrational and random motion
- Vibrational and translational motion
- Translational and random motion
-
Vibrational motion only
- Translational motion only
The correct answer is: D
Explanation
The cohesive forces binding the particles of a solid are strong enough to restrict their movement so that they are held together in a fixed point. They only vibrate and rotate about their fixed point.
